Air pollution may negatively affect brain and cognitive development in children and adolescents, a new study has warned.
Dispensed medication for psychiatric diagnosis can be related to air pollution concentrations, researchers from Umea University in Sweden said.
They studied the correlation between exposure to air pollution in residential areas and childrens’ and adolescents’ psychiatric health.
The study was performed by looking at register-based data, where dispensed medications of all Swedes are registered, together with Swedish National Register data of air pollution concentrations.
The entire population under 18 in four countries in Sweden was studied.
The findings were published in the journal BMJ open.
